tmr

Retriggerable monostable timer.

Timer is activated on every rising edge of input g in the following way:

1. On the rising edge of input g the following operations are performed:

l

Reading activation time from input t.

l

Zero setting of internal variable act (output act).

l

Set output o TRUE.

.

After t cycles are elapsed, from operations start, timer outputs are set in the following
way:

l

output o is set FALSE

l

output act stops on the last value reached

value)

2 . if, while the timer is active, input g became FALSE, timer goes on work normaly
3 . if, while the timer is active a new rising edge on input g is checked, timer executes a new cycle

repeating the operations starting from point 1.

When the timer is active, output o is TRUE, output act indicates the number of milliseconds elapsed from

operations start. When output o is FALSE output act is not significant.

Input

is read only in the cycle in which the rising cycle of input g is checked. Therefore, if

changes

while timer is enabled, output o is TRUE, the new value is not considered. This value will be used in the next
activation timer.

All times are expressed in milliseconds. Therefore, if input

is set 8, output o becomes TRUE for 8

milliseconds and output act changes from 0 to 8.
